4-Nitrodiphenylamine is a chemical compound from the group of diphenylamine derivatives and is isomeric to 2-nitrodiphenylamine and 3-nitrodiphenylamine .

Extraction and presentation

4-nitrodiphenylamine by condensation of 4-nitrochlorobenzene with aniline in chlorobenzene recovered.

Production of 4-nitrodiphenylamine

The worldwide production volume is up to 30,000 tons per year. This makes it one of the chemical substances that are produced in large quantities (" High Production Volume Chemical ", HPVC) and for which the Organization for Economic Cooperation and Development (OECD) collects data on possible dangers (" Screening Information Dataset ", SIDS).

properties

4-Nitrodiphenylamine is a yellow, flammable solid that is practically insoluble in water.

use

4-Nitrodiphenylamine is used as an intermediate in the manufacture of the rubber anti-aging agent N - (1,3-dimethylbutyl) - N '-phenyl-p-phenylenediamine.
